I tried all render settings (From fastest to fantastic), but the flashlights and other lights do NOT work for me. I've checked the internet for solutions, but the only one I found was about steam not managing graphic cards. That doesn't work, since I'm using a laptop and it uses Intel HD Graphics.

Help, please.
